IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 9,882, dated July 26,1853.

To all whom it may concern:

Be it known that I, JACOB H. OAROIHERS, ofDavidsburg, in the county ofBlair and State ofPennsylvania, have invented a new and useful Machinefor Planting Corn; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, forming part of thisspecification, in which the several parts are represented as follows:

Figure] is a plan of the machine. Fig. 2 is a side elevation of thesame. Fig. 3 is a vertical section upon the line w 00 of Fig.1. Fig. atis a front elevation of the tooth, showing the manner of securing thepoint.

Similar letters in the several figures refer to the same part of themachine.

The nature of my invention consists in connecting the hoppers andplanting apparatus with two arms movable about the rear bar of themachine, so that the planter can be operated upon uneven .ground, and bemade to pass readily over obstructions without interfering in any mannerwith the regularity of its operation; and, also,in theconstructionofthedrilltubes with movablepoints, so as to be readily replaced when fromlong use they become too worn for service.

In the drawings, A is the frame, movable upon the wheels B B O, whichare so constructed as to be adjustable vertically for regulating thedepth of the teeth D.

The planting apparatus consists of the shaft E, having at each extremitya roller, F, and in the middle the wheel G, which produces a rota rymotion of the shaft by the forward motion of the machine. This shaft Eis connected with the arms H by straps, which surround the shaft, andhas a motion about the rear bar, I, by

reason of the hinges b b, which attach the arms II to the rear bar. Thehoppers K are also fastened to the arms H, so that they are influencedby the motion of the shaft E about the bar I, as will be hereinaftermore fully explained. The rollers F are partially surrounded by thestraps c, which proceed from the bottoms of the hoppers and fit closelyto the surfaces of the rollers. The lower portions of these rollers,with their coverings 0, rest in therecesses d of the frame A, which openat the bottom into the hollow teeth D. The teeth are constructed as seenin the drawings the permanent portion having in its face the openingsff, the large one to admit the rivet g on the movable point, after whichthe necks of the rivets g g are pressed into the slots f, thus holdingthe point perfectly secure.

In the bottom of each hopper is the slot h, one-half of which is coveredby the slide t,- and -on the face of each roller are four recesses,

placed at the distance of ninety degrees from each other, twoconstructed to pass under the slide *5 and the others under the openportion of the sloth at each revolution of the roller. These recessesare capable ofholding the three grains of corn necessary for the hill,and when the slide 2' is in position the recesses passing under it areinoperative, so that but two hills of grain are planted at eachrevolution of the wheel G.

The operation of my machine is as follows: The wheels B B C are firstregulated to the depth the teeth Dare to sink and the team attached atP. The teeth D, which are the proper distance apart, make the furrows asthe machine moves forward, and the rotary motion of the wheel G revolvesthe rollers 1* within the casing c, causing the recesses in the face ofthe roller, as they come under the slot h, to receive three grainsofcorn, which it carries round and drops through the drill-tube into thefurrow. The wheel G is of the proper diameter for dropping the corn sothat the hills shall be three feet apart. Should it be required to formthe hills so as to be separated but half that distance, we remove theslides 1 allowing the opposite recesses to operate so as to produce thedesired effect. It' in the progress of the machine an obstruction shouldbe met with or the ground be uneven and irregular, the wheel G willaccommodateitself to the surface, raising the shaft E and hoppers K, atthe same time continuing the revolution of the rollers F, so that theregular distribution of the grain shall not be impeded. Should it bedesired to suspend the planting at any time, the lever m is moved to theright, operating the levers a and a and driving their pointed armsp andpinto the holes 1" in the sides of the wheel G, so that it becomeslocked, the shaft E ceases to revolve, and the rollers F nolongeroperate. The brake is removed by moving the lever m in theopposite direction, and the planting proceeds as above described.

The principal advantage of my machine consists in the connecting of thewhole planting apparatus to the swinging arms H, so that the operationof the machine can never be interrupted by the uneven nature of theground, thus causing the rollers F to revolve and deposit the properamount of grain in the exact position required, without regard to theobstructions met with in the progress of the machine.

lhe ease with which the planting apparatus is thrown out of gear is alsodeserving of notice,it being accomplished by the simple movement of alever-within the immediate reach of the driver.

The addition to the ordinary drill-tooth of the movable point is,Iconsider, an important feature in my machine. The two slots into whichthe necks of the rivets g g are pushed will always hold the point firm,for the reason that in use the tendency of the tooth-point will alwaysbe upward, and consequently the points will be self-tightening.

What I claim as my invention, and desire to secure by Letters Patent,is-

The method of stopping the seeding apparatus by grapplingthe peripheryof the drivingwheel in the manner herein described.

In testimony whereoflhave hereunto signed my name before two subscribingwitnesses.

JACOB H. OAROTHERS.
